Embodiment
Below in conjunction with embodiment, Water Level in Foundation Pit inspection well middle water level automated watch-keeping facility of the present invention is described in detail.
Embodiment:
Contrast Fig. 1 carries out Plant arrangement: the ball float 2 fastening vertical body 3 is put into water-level observation pipe 1, other end one end having been lain in the slotted line 4 with length mark on ball float 2 is by the pulley 5 at water-level observation mouth of pipe place and be connected with elastic stretching unit 6 by the meshing wheel of self-recorder 7, ensures that ball float is in nature and bubbles through the water column state while that adjustment elastic stretching unit making slotted line as far as possible exceptionally straight again.Data processor 8 is connected with self-recorder 7 by signal wire 15, automatically uploads transmitter 9 and is connected with data processor 8 by signal wire.
Water-level observation mouth of pipe place elevation measured by prior spirit-leveling instrument, after automated watch-keeping facility has been arranged, reads the distance to the mouth of pipe below ground, with formula: H by length mark on slotted line
water=H
mouthful-△ H calculates underground water table elevation.(in formula: H
water-underground water table elevation, H
mouthful-water-level observation mouth of pipe elevation, △ H-ground water level is to the distance of the water-level observation mouth of pipe).The ground water level elevation Input Data Process 8(processor calculated is adopted the NUC100 microcontroller of commercially available new Tang science and technology).
When automated watch-keeping facility is in running order, when decline of groundwater level, ball float 2 moves down thereupon, simultaneously because the Action of Gravity Field of vertical body 3 pulls slotted line 4 to make it to extend, elastic stretching unit 6(is shown in Fig. 3) sense the pulling force of slotted line 4, outwards release slotted line 4.After water level stopping decline, ball float 2 position are fixed, the pulling force of slotted line 4 disappears, and elastic stretching unit 6 stops discharging slotted line 4.In slotted line 4 elongation process, self-recorder 7(is shown in Fig. 2) record slotted line 4 length by meshing wheel movement simultaneously, and this length data is fed back to data processor 8, also feed back the mark of a negative sense movement simultaneously, movable length is added in original altitude figures as negative increment according to mobile mark by data processor 8, obtain new water level elevation data, and these data are flowed to automatically upload the product that transmitter 9(transmitter adopts Shanghai Drery Information Technology Co., Ltd.:
gPRSDTUD800wireless data transmission terminal) send to monitoring central server.So far an automatic gatherer process of data is completed.
When underground water table rises, ball float 2 moves up, slotted line 4 is loose, tension balanced on line disappears, automatic tightening slotted line 4 under the screen resilience effect of elastic stretching unit 6, now the incremental data of a forward movement is just fed back to data processor 8 by self-recorder 7, and data processor 8 just superposes a positive increment in existing altitude figures, and sends to and upload transmitter 9 and upload to monitoring central server.So constantly circulation repeatedly, carries out the automatic collection of underground water table altitude figures.
The concrete structure of self-recorder 7: as shown in Figure 2, slotted line 4 passes through between upper and lower meshing wheel, meshing wheel 11 is driven to rotate when slotted line 4 moves, the pinion wheel 14 coaxial with lower meshing wheel 11 drives gear wheel 12 to rotate, the number of teeth of pinion wheel 14 is 1/10 of the gear wheel number of teeth, the girth 20cm of meshing wheel 11, when slotted line 4 moves 20cm, meshing wheel 11 turns around, and gear wheel 12 rotates 36
o, the angular transducer 13(coaxial with gear wheel 12 selects the P4500 angular transducer of Shenzhen meter Lang company) and the data that angle changed are converted to length variations signal by the relation of 0.5556cm ╱ degree and send data processor 8 to by signal wire 15.
The concrete structure of elastic stretching unit 6: as shown in Figure 3, the principle of work of elastic stretching unit 6 is similar to the principle of steel tape, and one end of coil spring (disc spring) 17 is fixed on the stationary shaft 18 of pedestal 16, and the other end is connected with slotted line 4.When inspection well 1 middle water level declines, the Action of Gravity Field of vertical body 3 pulls slotted line 4, and the slotted line 4 in elastic stretching unit 6 is drawn out, and disc spring 17 tightens up compression; When water level rises, the pulling force on slotted line 4 reduces, and the force of compression release of disc spring 17, slotted line 4 is retracted in elastic stretching unit 6.
The adjustment thread of elastic stretching unit 6 is positive and negative 1m, upload transmitter 9 the transmission frequency can as required voluntarily by the hour or minute setting.
During apparatus of the present invention work, the vertical body 3 of constant weight is lain in below ball float 2, on the groundwater level allowing ball float 2 float in water-level observation pipe 1, slotted line 4 with length mark is connected ball float 2 and elastic stretching unit 6, when ball float 2 moves up and down with the rise and fall of underground water, elastic stretching unit 6 can automatically extend and shorten slotted line 4, self-recorder 7 can record the variable quantity that slotted line 4 extends and shortens, the variable quantity of slotted line 4 is added to and initially descends water level elevation just obtains the eustasy data of underground water table by data processor 8, transmitter 9 by process after data upload to monitoring central server, automatically the WATER LEVEL CHANGES curve map in water-level observation pipe is drawn.So constantly circulation repeatedly, carries out the automatic collection of underground water table altitude figures.
